MACHINE FOR SECURING LOCKING PLATES AND PINS IN BED RAILS AND POST S.

SPECIFICATION forming part of Letters Patent No. 579,836, dated March30, 1897. Application filed September 30, 1896. Serial No. 607,449. (Nomodel.)

To Ml whom it may concern;

Be it known that we, Aeusrus D. NEW- BERRY and WILLIAM J. MELVIN, ofFayetteville, in the county of Cumberland and State of North Carolina,have invented a new and Improved Machine for Securing Locking Plates andPins in Bed Rails and Posts, of which the following is a full, clear,and exact description.

Our invention relates to a new and improved machine for securing lockingplates and pins to bed rails and posts.

It consists, essentially, of a slide operated by a foot-lever andcarrying punches placed to register with the holes in the locking-plate,and also of feed-chutes adapted to receive the pins for securing saidplates in place.

It also consists of certain mechanism for locking and holding the platesand rails in proper position for the work; also, in other details whichwill be clearly pointed out in the following specification.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side view, partially in section, showing our device. Fig.2 is a plan view of the operating mechanism thereof. Fig. 3 is across-sectional view through the feed-chutes and including only thetable and operating portions, and Fig. 4 is a longitudinal sectionthrough similar portions.

The object of our invention is to provide means by which the lockingmechanism of a bedstead may be quickly secured in place thereon and todo the work more efficiently than can be done by hand.

A framework A of any suitable shape is provided for supporting andholding the mechanism. To this framework is pivoted a weighted lever B,which has its pivot at b and is connected at B with a link orconnectingrod 0, connected at its lower end to a footlever D, pivoted atD to the frame of the machine, the opposite end of this lever having atD a plate for the foot of the operator of the machine.

The lever B at one end is triangular-shaped,

forming a bell-crank, to which at B is pivot-ed a short link E. Thislink E at its rear end is connected, by means of a stud E, with across-bar E of a slide E. This slide E at its forward end carries aseries of socketpieces F, adapted to receive the punches F. These aresecured to the frame by set-screws F which will securely hold them inposition.

The socket-pieces F may be dispensed with by having the holes in thecrossbar of the frame of such a size as to receive the punches andforming the sockets in the bar itself.

The forward ends of the punches F enter guides G. These guides have acentral hole throughout their length in which the punches snugly fit.Upon the upper side there is a slot G connecting with the feed-chutesand through which the pins for securing the plates in position are fed.These feed-chutes H (shown in section in Fig. 8) consist of a troughplaced at an angle and adapted to receive the pins. The pins h (shown inFigs. 3, 4, and 5) consist of round pins without any heads thereon. Theyare placed in the chutes, as shown most clearly in Fig. 3, the pinsextending across the chute and resting one against the other. In thisposition they will roll down the chute'as fast as the lower ones aretaken away.

The chute H is made adjustable by having the side H adjustable upon thebody of the chute. This is attached to a cross-slide H which slides in adovetail groove in the body of the chute. To this slide is secured alocking-screw H operated by the hands and adapted to clamp the slide inany position desired. In this way the width of the chute may be adjustedto the length of the rivets or pins used.

The knee or table I, which is placed just in front of the chutes, issupported at each side of the machine by the adjust-able bars I. Thesebars I have a slot 1 through which passes a bolt 1 which permits ofadjusting the table vertically. To secure a more accurate adjustmentthan is readily possible by this means, we have provided a secondadjustment, consisting of a screw J, which works in a nut J, attached toor formed as a part of the frame A. This bears against the under side ofthe table I. In adjusting the elevation of this table I the screws I areloosened, and the table may then be moved up by screwing upon the boltJ. This will force the table up to exactly the point desired. hen thispoint is reached, the bolts I may be tightened, thus securing the tablein position. The lowering of the table may be accomplished in a similarway, the screw J being used to get an accurate adjustment. Upon theupper surface of the table I is attached a cross-bar K. This is attachedtO a bottom member K, which slides in a dovetail groove K formed acrossthe table I. This cross-bar K is adapted to be moved to or from theguides G to make room for the different thickness of the rails and poststo be used in this work. The cross-bar K is adapted to receive thethrust of the device in forcing the pins to place.

In Fig. 4 the locking-plate is shown at L and the rail to which it is tobe secured at L. Pivoted to the lug J, forming the nut for the screw J,is a block M. This block may swing slightly in a horizontal direction.Between the upper end of this block and the cross-bar I of the table Iis placed the locking-plate L. The punches F are advanced by pressingdown upon the leverD until theypass through the holes in thelocking-plate. This assures the accurate placing of the plate. Whileheld upon these punches, the swinging plate M is forced against thelocking-screw M, which passes through the lugs I upon the bottom of theplate I and bears against the surface of the plate M. This securelyholds the locking-plate in position. The rail L, which has beenpreviously slotted for the reception of the plate and bored for thereception of the pins, is then placed over the plate. The lever D isthen brought to its extreme upper position. This withdraws the punches Fto the position shown in Fig. 4 and permits the pins in the chutes todrop in each guide. The foot-lever D is then forced down. This advancesthe punches F, carrying with each a locking-pin. This is forced into thehole previously prepared in the rail L and through the holes in thelocking-plate L. The lever D is then permitted to rise, but not to itsfull extent. It will be noticed that there is a notch A, formed in aplate attached to the frame of the machine and forming a guide for thesaid lever. This notch is adapted to receive the lever and prevent itsfurther rise when the same is thrown to that side of the slot. This riseof the lever will permit the retraction of the punches F sufficiently toentirely clear the bed-rail, but not so far as to permit the pins in thefeed-chutes to drop. The object of this is. to permit the advancing ofthe punches F for accurately centering the locking-plate when the sameis inserted and the plate and rail have been thus centered and clampedthe lever D is thrown out of the slot A and permitted to rise in theposition shown in full lines in Fig. 1. This retracts the punches to theposition shown in full lines in Fig. 4 and permits the feed-chutes tofill the guides with locking-pins.

Our device may be used for inserting the locking-pins in the posts ofthe bedstead as well as inserting the pins for holding the locking-platein position. In this case a single pin only is inserted, or two, ifdesired. For this work one or two of the punches shown in the drawingsshould be removed and one or two only used, as the case may be. Theposition of the table and also of the slide K would be adjusteddifferently from those shown in the drawings. The rail should be placedthereon in such a position that the hole may be brought to register withthe punch being used. One or two of the chutes only should be suppliedwith pins and the pins fed forward and placed in the post in the samemanner as heretofore described for locking the plate in the rail.

IVith this mechanism it is possible to accurately lock the pins in therail and in the post, and the distance to which they will be forced intoeach can be accurately adjusted, and thus avoid trouble arising fromforcing the pin too far and thus breaking out the wood from the oppositeside of the plate or of not forcing the pin far enough and thus securinga poor hold upon the plate.

As indicated in Fig. 4, the hole in the rail for the reception of thepin is not bored entirely through. The same is true of the post whichreceives the pin adapted to engage plate to secure the rail to the postwhen setting the bedstead up.

The lever B is weighted by having a block 13 placed upon one endthereof. This block is adjustable and intended to return the parts tothe position shown in Fig. 1 and is adj ustable upon the lever also,that the force thereof may be made whatever desired.

\Vith our device it is possible to do much better workthan can be doneby hand and also much more rapid work. The operator can be certain ofhaving the locking-pins accurately placed and without any danger ofinjuring the wood portions of the bedstead.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1.
